FILE FOR INDEX-CARDS.

SPECIFICATION forming part of Letters Patent No. 525,947, datedSeptember 11, 1894.

Application filed May 28, 1894.

To all whom it may concern.-

Be itknown that I, ALEXANDER DOM, a citizen of the United .States,residing at Mount Healthy, Hamilton county, State of Ohio, have inventedcertain new and useful Improvement in Files for Index-Cards, of whichthe following is a specification, reference being had to theaccompanying drawings.

My invention relates to that class of files in which the index or othercards are retained within a box or drawer by means of a rod passedthrough the front end of the box or drawer and through suitableperforations in the cards, the object being to provide an efficientmeans whereby any desired card may be readily inserted or removed fromthe file,

as will more fully hereinafter appear.

In the accompanying drawings:-Figure 1, is a perspective view of acabinet-file showing one of the drawers drawn out and sectioned, thesame being provided with my improvements. Fig. 2, is a rear face view ofthe lock-plate removed from the front end of the drawer, and showing thefiling-rod locked in position thereon and the preferred form of lockingmechanism. Fig. 3, is a view similar to Fig. 2, with the filing-rodturned in position to be removed or disengaged from the lock-plate. Fig.4, is a View similar to Figs. 2 and 3, showing one modification of thespring mechanism for automatically turning the file-rod and looking itto the plate. Fig. 5, is a top view of the actuating log on thefile-rod, and Fig. 6, is a side view of same.

In the drawings, A, represents a cabinet having drawers, B, the latterbeing adapted to receive and retain the index-cards, O, or other matter,said cards being retained therein in an adjustable position by means ofa rod, D, passed through perforations in said cards.

' It is also preferred to employ one or more followers, E, within thedrawer or case, said f01-' lower having the rod passed through it, asshown; but, if desired, said follower may be dispensed with as thelatter constitutes no part of my invention.

My invention consists of suitable spring mechanism for automaticallyimparting a partial rotation to the file-rod and for locking the latterto a plate secured to the front end of a drawer or case; and, with thisobject in Serial No. 512,626. (No model.)

View, I have provided the plate, a, which is secured to the front end ofthe drawer, said plate having an elongated opening, a, as

shown. To the inner face of this plate are attached the spring-actuatingarms, I), b, which latter, when in their normal position, extend acrossthe opening a Said arms may be formed of any suitable material and maybe of any desired configuration, and may also be attached to the platein any desired manner. In the drawings I have illustrated the arms I) ascomposed of spring-wire bent as shown and secured to the plate by meansof a headed rivet, b the rear end b of the wire being rigidly attachedto the plate. It is also preferred to provide said plate with a headedrivet or projection, b, to retain the free end portion of each arm inproper position. If desired, the arms, I), may be formed of a singlepiece of spring material bent centrally upon itself, and suitablyconnected to the plate, as shown in Fig. 4, in which event a suitablelug, 0. may be struck-up from the plate to retain the free end portionsof said arms a suitable distance apart.

The rod, D, is provided with a headed portion, (1, and an angular orwedge-shaped lug, 61 the latter being approximately flat incross-section. The rear portion of this lug is a slight distance fromthe head of the rod, forming a space or recess, e, which is occupied bythe edge of plate a when said rod is in a locked position, as shown inFigs. 1 and 2.

The operation of my invention is as follows: To insert the rod, D, theoperator manipulates it in such a manner as that the flat portion of itslug (1 will align with the elongated opening a in the plate; and, assaid rod and its lug is passed through said opening, the wedge-shapedportion of the lug will act upon the arms I), forcing them outward asshown in Fig. 3 until said lug has passed the inner face of the plate atwhich instant the resiliency of said spring-arms will turn said lugacross the face of the opening, as shown in Fig. 2, in which positionthe rod is securely locked to its plate. To limit the rotatory movementof the lug and rod, I have provided the lugs a, one on each side of theopening 0, as shown. To remove the filingrod, the operator grasps thehead, 01, of said rod and gives it a partial rotation until. the lngdcomes into contact with the projections, to, at which time said lugaligns with the opening a as shown in Fig. 3, and may then be withdrawn.

The advantages of my invention are apparent, aflording as it does aneconomic and eificient device for locking the filing-rod to positionwithin a drawer or case. The operation of the locking-device is suchthat the filingrod can be inserted and locked, or removed, in a momentstime.

What I claim as new, and desire tosecure by Letters Patent, is-

1. A file-case having a plate attached to its front end portion, saidplate having an elongated opening, in combination with a rod having alug thereon adapted to pass through said opening, and spring actuatingmechanism impinging against said lug, said rod having a longitudinal androtatory movement within said plate, for the purposes set forth.

2. A file-case having a plate attached to its front end, said platehaving an elongated opening therein, and lugs to on its inner face atthe sides of said opening, in combination with a rod and lug thereonadapted to pass through said opening, said rod having a longitudinal androtatory movement Within said plate and spring actuating mechanismimpinging against said lug, as and for the purposes specified.

3. A file-case having a plate a attached to its front end with anelongated opening in said plate, the latter having the spring-arms I)attached thereto on its inner face, said arms projecting across saidopening, in com-' bina'tion with the rod D having a lug d thereon, saidrod having a longitudinal and rotatory movement within said plate,substantially as set forth.

4. A file-case having a plate (1 attached to its front end with anelongated opening 01, therein, said plate on its inner face having thelugsu and spring-arms b attached thereto, and lugs for limiting theinward movement of said arms, in combination with rod D having head d,lug d and a space e intervening between said head and lug, said rodhavinga longitudinal and rotatory movement within said plate, for thepurposes set forth.
